Jason Garrett says Cowboys not giving up on DE Randy Gregory

Dallas coach Jason Garrett says the Cowboys are standing by defensive end Randy Gregory, who was suspended indefinitely this week for violating the NFL's substance abuse policy.

It's the fourth time the troubled player has been banned by the league.

"The way it's been explained to me is sometimes relapse is part of rehab," Garrett said at the NFL scouting combine Wednesday.  "Unfortunately, the NFL has this policy that sometimes suspends players in these situations. We'll continue to try to support him. I know he's working very hard to get his issues under control."

Garrett said Gregory is serious about overcoming his substance abuse problem and that's why the Cowboys aren't giving up on him.

Coming off his best season, Gregory won't be allowed to participate in the Cowboys' offseason program. He can only go to the team's practice facility to meet with the person in charge of his treatment.
